' I Application'filed March 6,1901.- swarm. 50,085. model.)

To aZZ whom it may concerm Be it known that we, GEORGE XV. EASSETT, residing at Middlebury, and RINALDO A.

' WHITTIER, residing at Hancock, in the county of Addison and State 'ofVermont, citizens of the United States, have invented a'certain' new and useful Gluing-Machine, of which the following is a specification, reference being had therein to theaccompanyingdrawings.

This invention relates to gluing-machines, the object in view being to provide a machine embodying,iu connection with an adjustable slat-holding rack, feeding mechanism for successively transferring theslats to the gluing mechanism and a gluing device comprising glue-applying disks adjustable relatively to each other and adapted to spread the glue upon the slats at various intervals and in lines extending parallel-to each other and transversely of the slat.

It is also an important object of thisinvention to provide means whereby the machine is adapted to accommodate slats of different lengths, widths, and thicknesses; also, to provide adjustable slat-carriers and operating mechanism therefor, and also to'construct the gluing mechanism in such manner that the glue-applyingdisks are capable of being adj usted relative to each other for the purpose of applying the glue at proper intervals to I each slat as it is moved by the feeding mechani'sm. I

Another object of the invention is to provide, in connection with reciprocatory actuailing-straps, carriers forming part of the feeding mechanism, which carriers are adj ustably associated with the actuating-bands for changing the throw of the carriers.

A further object of the invention is to provide a jointing-hammer which is connected with the same operating device which actuates the feeding mechanism, so that the said hammer and feeding mechanism will be simultaneously operated.

With the above andother objectsin view, which will be better understood as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described, illustrated, and claimed.

for guiding the hammer.

3 Similar numerals of reference denote like parts in all the figures of the drawings.

. The machine contemplated in this invention is especially designed with reference to the gluing and jointing of the comb frames or sections of a beehive, which frames or sec.- tions, as is well understood, are of open rec- 8o tangular form and which are ordinarily constructed from a slatl, (illustrated in detail in Fig. 10,) such slat consisting of a strip of wood of the necessary length, breadth, and thickness, which, preparatory to the formation of the comb frame or sections, is passed through a suitable machine, which forms therein the transversely-extending V-shaped kerf s 2, which define three of the corners of the comb frame or section, and the mortises o and tenons 3 at the extremities of the slat, which interlock with each other when the slat is folded and form a lock corner-joint.

The mechanism hereinafter described is adapted to apply glue tothe several kerfs 2 5 and ends 3 as they are fed outward by suitable feeding mechanism from a slat-holding rack, the extremities of the slat being subsequently forced into engagement with each other by means of a jointing-hammer, which [Q0 may be propelled with any desired force against the corner of the frame or section where the lock corner-joint occurs.

The machine comprises, essentially, a pair of end uprights 4, which are provided at the bottom with supporting base-timbers 5 and connected by suitable longitudinal framebars 6 and 7, the bars 6 forming a support for a series of slat-supporting rails 8, which rest upon the bars 6 and are secured thereto in any convenient manner. The rails 8 are preferably constructed of sheet metal and provided with upstanding flanges 9, upon which the slats slide as they move forward when actuated by the feeding mechanism.

The end frames 4 are further connected at their upper ends by a longitudinal hanger bar 10, provided with longitudinal slots 11 to receive clamping-bolts 12, which are inserted through the upper extremities of a pair of end guides 13 and providedwith thumb-nuts 14, so that the upper ends of the end guides 13 may be adjusted lengthwise of the hangerbar for varying the distance between the end guides and accommodating slats of different lengths, the parts 13 forming the ends of the slat-holding rack, as shown in Figs. 1 and 3. The lower ends of the guides 13 are adj ustably connected to a guard or presserbar 15, which is provided with slots 16 to receive clamping-bolts 17, provided with thumb nuts 18. Each of the end guides 13 is also connected to one of the longitudinal framebars 6 by means of a clamping-bolt 19, passthe upper and lower ends of the end guides 13 and at the same time rendering said guides adjustable toward and away from each other for accommodating slats of different lengths. The guard or presser-bar is providedwith a forwardly-extending flange 21, which serves to hold the slats downward in engagement with the gluing devices as the slats are successively moved forward by the feeding mechanism hereinafter described.

At their front edges the guides 13 are provided with face-plates 22 of greater width than the thickness of the end guides, so as to provide inwardly-extending flanges or stops 23, which will lie in front of the forward edges of the slats, as shown in Figs. 1 and 3. The rear edges of the slats are held by means of self-adjusting back-stops 24, each of which is provided with an angular flange 25, adapted to engage directly with the rear edges of the slats, as shown in Fig. 3, the body of each back-stop being provided adjacent to its opposite ends with inclined or oblique slots 26, which receive clamping-bolts 27, passing into one of the end guides 13. After placing a pile of slats within the rack the back-stops 24 are engaged with the bolts forming members of the clamping devices 27, and, on account of the inclination of the slots 26, the back-stops will gravitate toward the slats until the flanges 25 are brought into engagement therewith, whereupon the clamping device 27 may be tightened. In this way provision is rnade for accommodating slats of different widths.

The mechanism for feeding the slats to the gluing device comprises a plurality of slatcarriers 28, each of which comprises the upstanding flanges 29, preferably recurved at their upper edges to form the depending guide'strips 30 for engaging one of the members of the clamp whereby the carrier is secured to its actuating-band. The clamp consists of a plate 31, having upturned end portions 32, between which is received a cap 33 in the form of a plate having upturned edges or flanges 34, which are received behind the guide-strips 30 in order to render the clamp adjustable lengthwise of the slat-carrier. A clamping-screw 35 passes through the cap 33 and engages a nut 36, held between the clamp and cap, the lower endof the clamping-screw bearing against the body of the clamp 31, so as to force the latter into firm engagement with a portion of the actuating"- band 37, which passes through slots 38 in the bottom 39 of the slat-carrier, which slots are spaced apart, so as to allow a portion of the band to extend over the top of the floor or bottom 39 of the carrier, as illustrated in Figs. 6 and 7. By loosening the screw 35 the slat-carrier may be adjusted lengthwise of the actuatingband 37 for the purpose of varying the throw of the slat-carrier and accommodating the same to slats of different widths. The slatcarrier is also equipped with a feed-dog 40, which for convenience is shown in the form of a spring having one end secured to the body of the carrier and its free end extended sufficiently above the top of the carrier to engage the lowermost slat in the slat-holding rack in a manner which will be understood by reference to Fig. 2.

Motion is imparted to the actuating-band 37 by means of a pair of oscillatory members 41 and 42, preferably in the form of rollers suitably journaled in or on the machine frame just beneath the rails 8 and carriers 28, as shown in Fig. 2. Each of said rollers is provided with a longitudinal groove 43 to receive one of the extremities of the actuating-band 37, which may be adjusted to any point lengthwise of the groove 43and held by means of a wedge 44 or the equivalent thereof, which is inserted into the groove. In this way provision is made for the lateral adjustment of the slat-carriers, so that they may be brought into any desired relation to the slats upon which they operate. The roller 41 is reduced by grooving the same, as shown at 45, to receive a roller operating belt 46, which extends downward and connects with an operating device, preferably in the form of a foot-lever 47, fulcrumed at 48 on the machine-frame. By depressing the lever 47 rotary motion is imparted to the roller 41, so as to cause the actuating-bands 37 and the slat-carriers to move forwardand ,feed a slat to the gluing mechanism. The

band is retracted by theroller 42, which is provided with an inclosed actuating or retracting spring 49, having one end con nectedto the body of ethe roller and its other end connected to the shaft upon which the roller is journaled, as shown in Fig. 1

The gluing mechanism comprises a gluetrough 50, having a lower compartment for holding hot water and an upper compartment for containing the glue in liquid form,

the two compartments being divided .by a dished partition 51, centrally concaved-to agree with the circumference of the gluingdisks, as shown in Fig; 2, so that the disks willtake up the .glue as long as any glue remains in the trough. The trough50-may be of any suitable length and is adapted to extend beneath all of the gluing-disks.v Arranged above the bottomof the glue-receiving compartment ofthe trough-is a shaft 52, extending lengthwise of the trough and having-mounted'thereon a series of glue-applying disks 53, each of which isprovided with a set-screw 54, so that said disks may be adjusted relatively to each other and placed at any point on the shaft 52, according to the.

location of the kerfs 2 of the slat 1. Each disk except the endone has its periphery beveled or chamfered from only one side, as shown at 54, in order to apply glue only to one of the inclined sides of the kerfs 2, it only .being necessary to glue one of the walls of each kerf. As the shaft 52 revolves the glue-applying disks take up the glue and spread it within the kerfs 2, said glue-applying disks being actuated to revolve preferably in a direction opposite to that in which the slat is fed by the slat-carrier. Motion is imparted to the shaft 52'by means of a belt 55, which passes around the rollers 41 and 42 and also one or more times around a small drum 56 at one end of the shaft 52, as illustrated in Fig. 8, wherein. the glue-trough is shown as provided at one end with a' fillingnozzle 57. Beneath the trough 50 is arranged a suitable heater 58, the same being supported upon a vertically-adjustable shelf 59, which enables different forms of heaters to be employed and raised or lowered, so as to have more or less effect upon the water within the lower compartment of the gluetrough.

After the slats have had the glue applied thereto in the manner described they are folded one by one into the usual rectangular form and placed by hand upon a table or rest 60, arranged near one end of the machine and at or adjacent to the front thereof, as shown, said table being provided with the upstandingflanges 61 for properly positioning the frame or section. Above said table or rest is arranged a vertically-reciprocating jointinghammer 62, which is mounted to slide between the fianges 63 of a pair of parallel guides 64. The inner flanges 63 of the guides by meansof a bolt or other suitable fastener 66 and atits lower end to the operating device 47, the said hammer-operating connection passing at intermediate points around suitable direction -pulleys 67, journaled on the machine-frame. v. The hammer is moved downward by pressing upon the foot-lever 47, and when the foot-lever is released the hammer is moved upward by means of a retracting-spring 68, connected at one end to the hammer and at the opposite end to a fixed part of the frame. I

From the foregoing description it is thought that the operation of the machine will be readthefoot-lever 47 operates the feeding and gluing mechanisn1s,and at each stroke of the lever 47a slat is fed forward by-the slat-carrier and glue applied thereto by means of the glue-applyingdisks 53. The operatorthen grasps the slatand folds the same into're'ctangular shape and places the same on the rest or table 60, at the same time bringing the interlocking extremities of the slat into alinement with each other. In the next stroke of thefoot-lever 47 the jointing-hammer 62 isthrown downward, so as to jam the interlockin g extremities of the slat firmly together, and simultaneously therewith an additional slat is fed forward by means of the slat-carriers. Inv this mannerthe slats are quickly fed forward, glued, and formed into rectangular shape and securely united at the lock-corner, enabling the comb frames or sections to bemanufactured with great rapidity. After the desired number of frames or sections have drawn from the glue-trough by means of adrain-spout 69, inclining downward from the bottom thereof and provided-witha suitable stopper 70.

It will be apparent that the machine hereinabove described is susceptible of considerable variation in detail without departing from the principles of the present invention, and we therefore reserve the right to make such changes as come within the scope of the appended claims.
